Effect of refrigerant amount on electric output of a thermoelectric generation system installed with a thermosiphon type heat exchanger

Abstract

A thermoelectric generation system (TEG) is well known as an exhaust heat recovery system. Also, a thermosiphon type heat exchanger is known that it has higher heat transfer performance using circulation of refrigerant with evaporation and condensation cycle. In case of using the heat exchanger for TEG, it is important to optimize refrigerant amount. In this study, the effect of refrigerant amount on heat transfer and the electric output has been investigated in the TEG with the thermosiphon type heat exchanger.
